The t value at the significance level of .05 and df of 8 and from appendix F is 1.812. The decision rule is to reject the null hypothesis because the test statistic is greater then 1.812. Step 3: According to Appendix F‚ we can assume that P 1.744)‚ there is insufficient evidence to reject the null hypothesis. P-value Approach: Since the P-value is less
